Empirical correlates of the MMPI-2 Restructured Clinical (RC) Scales in mental health, forensic, and nonclinical settings: an introduction.

We introduce 3 studies of the empirical correlates of the MMPI-2 Restructured Clinical (RC) Scales: a study by Arbisi, Sellbom, and Ben-Porath (2008/this issue) that expands the range of correlates of the RC scale in mental health settings; an investigation by Sellbom, Ben-Porath, Baum, Erez, and Gregory (2008/this issue) of the empirical correlates of the scales in a forensic setting; and a study by Forbey and Ben-Porath (2008/this issue) examining convergent and discriminant validities of the RC scale in a nonclinical setting. To serve as a general introduction to the 3 new empirical studies presented in this special section, we begin with a review of the existing literature on the RC scales and briefly describe these studies.
